The comblned bucket elevator and con;

veyer disclosedin Fig. 7 represents a typicalinstallation as ordinarily applied in a canning factory and comprisesa pair of laterally spaced parallel endless chains 11 securedto corresponding opposite ends of conveyer buckets 7, and coacting with sprockets 8, 9, -These'sproc'kets 8, 9, 22

are arranged in laterally spaced pairs mounted upon counter shafts which are sup ported in suitable bearings secured to the millframingt At least one pair of the sprockets 22 is ordinarily made adjustable transversely of the chains'll in "order to enable the taking up "of excessive'slack in'the chains 11. One of thesprocket counter shafts is drivingly connected to a motor 21 or other'sourceof power by means of suitable gearing, thus enabling the motor to gradually advance the endless series of buckets 7.v The advancing buckets 7 are automatically successively filled with material,

elevated and brought into engagement with an automatic tipping device 20 which discharges the material from'th'e buckets 7 into a su table receptacle. 7 s

The automatic measurlng and feeding device which forms the subject of thepresent invention and which is shown in detail in Figs. 1 to 6 mclusive, comprises in general a main frame 10, in wh1ch are ournaled four parallel cross shafts to the forward one of which the laterally spaced front sprockets 9 are attached, tothe rear one of which the laterally spaced rear sprockets 8 are attached, and to the two intermediate of which the laterally spaoedrollers 5,, l are secured.

' The parallel conveyer chains 11 to which the buckets 7 arepivotally securedby means of cross rods 18, coact with the teeth'of the sprockets 9, 8 and are adapted-to gradually transport the buckets 7 successively through Tithe region below the rollers 5', 4. The conveyer buckets 7 are of standard construction and preferably have perforated bottoms. Alternate buckets 7 have tiltingteeth 23attached to corresponding ends thereof while the intermediate buckets 7 have similar tilt ing teeth 23 attached to their opposite .corresponding ends. 'The conveyer chains 11 are supported and guided in the region below the rollers 53, ft by means of lower chain guides 28 which are secured tothe side members of the frame 10. The buckets 7 are guided and restrained against upward displacement while passing through the region below the rollers 5, 4, by means Of a pockets '2 formed therein.

necessary guards may also be prqvlded, such stationary front guide 12 and a stationary rear guide 13, these guides being adjustably secured to cross elements of the frame 10.

Resting directly upon the rollers 5, 4 and located above the lower horizontal stretch of the bucket conveyer, is an annular body of revolutio or ring 1 which has a series of slightly tapered, equally spaced, measuring The pockets 2 are spaced apart from center to center, distances equal to thedistances between the centers of successive conveyer buckets 7.

veyerchains 11. The ring 1 is thus revolved upon the rotaryrollers 5, 4 directly by the moving conveyer, receiving power simultaneously from both .of the conveyer chains 11.

Within the ring 1 is located a stationary Shopper 3 having upwardly open end portions which pro ect beyond the ends of the ring 1.: The hopper 3 has a lower discharge opening which is communicable directly with the inner openends of the successive pockets 2. The front and rear walls Ofthe hopper discharge opening are provided with adjustable plates 29. which may be shifted relatively to the ring 1.; The-hopper?) is also provided with a'downwardly depending stationary guard plate 14 forpreventing material from rolling beyond the feeder dis- -charge'opening,.see Figs. 4,5 and 6. A

wash'water supply pipe 15 may be located above the hopper 3 as shown in these figures,

andmay be readily removed and inserted. The hopepr 3 is detachably secured to the side members of the main frame 10 by means of manually operable clamping. nuts 27' and swivelbolts 3O, and may be freely removed endwisefrom within-the ring 1 upon releasc'of the clamping nuts 27. :Journa led 1 thelower port on of the hopper 3 I is a cross-shaft to which issecured a pair of .wardly from about the horizontal central plane of the ring 1, to a plane somewhat beyond the rear wall of the hopper discharge A suitable stationary guard '16 18 of screws '25, a manually operated nut 24 and a swing bolt 31,; this guard serving to prevent foreign substances from dropping Other guards havingji been omitted order to avoidcomplication of thef'disclosure. *The various surfaces which are subject to-:oon

The buckets-7 after having been emptied, are transported past the several pairsof sprockets 22 and are eventually carried past the lower 'frontsprockets 9 by means of the eo ve'yerehains ,lI. As the empty buckets 7; move into the region below the rollers, 5', {they gradually: pass the lower extremity '-of the wall 17' and the bucket cro'ssfirod's 18 engage the successive peripheral notches19 of 'the'rin g 1. The

While-the buckets 7 'arefthu s advancing toward the feeder, the ring. 1 is being gradually revolved in a clockwise direction upon the rollers-5 4, by virtue offthe 'coaction or ring 1' rotates, the measuring pockets 2 are the sprockets QG' withthe longitudinally moving chains -11*oftheconvey er.

It will also be obvious that the feeder positively measures the material and desired to limit the invention to the exact details herein shown for obviou modifications may occur to persons skilled inthe art.
